E. WENDER MOVABLE CLAMP FOR METALLIC ROOF COVERINGS Filed Sept. 6, 1930 Patented Oct. 11, 1932 .UNITE TE MOVABLE CLAMP FOR METALLIC ROOF COVERINGS Application filed September 6, 1930, Serial No. 480,123, and in Germany August 2, 1929.

The invention concerns a clinger for erect grooves at a flexible metallic roof covering. The novelty consists in the clinger being movable and composed: of two parts, one of 6 which is firmly connected to the roof base, while the other part is grooved or by other means joined to the covering, with allow ance for displacement along and transverse to the slope of the roof.

Figs. l-12 show examples of difierent executions of the invention.

Part a of the clinger is in the usual way firmly connected to the base of the roof which may consist of any material whatever. The erect standing part b is grooved or by other means joined to the covering, which also s cures the possibility of displacement in equal directions between covering and base, the allowance for displacement along and vertical to the slope of the roof being secured bet-ween parts a and b of the clinger. Even in the case of strong winds the covering will neither be untiled or ripped off the base, nor will it ever sufl'er from change of temperature, on

account of the movable connection between parts a and b of the clinger, since the covering may expand and contract, wandering so to speak on the base of the roof.

Fig. 1 is a perspective view of a piece of 39 roof with a metallic covering.

Figs. 2 and 3 show a lateral view of the clinger, vertical to the direction of the erect groove and the slope of the roof.

Fig. 4 is a view of the clinger vertical to the direction of the erect groove and the slope of the roof. r

Fig. 5 is a lateral view of another execution of the invention exactly as in Figs. 2 and 3.

Fig. 6 is another view of Fig. 5 in the same manner as Fig. 4:.

Figs. 7 and 8 show still another execution in the same manner as Figs. 2 and 4.

Figs. 9 and 10 show the invention anew in another execution similar to Figs. 2 and 4, except that part a is shown in Fig. 9 in crosssection and inFig. 10 in longitudinal-section.

Figs. 11 and 12 show still another execution of the Clinger the views being also verticafl to or in the direction of the slope of the roo 1 The invention is also marked with the let ter a in Fig. 1, with reference to its part a fixed to the base of the roof. From Fig. 2 results that the clinger composed of the two principal parts a and b is placed between two ends of the roof covering joining laterally to one another and that part a is firmly con- V nected to the roof covering and part b to the two ends of the covering forming an erect groove.

Fig. 3 shows the clinger with-its part h and the two adjacent ends of the roof cover ing ready grooved. Nevertheless, it is not absolutely essential that part b is grooved together with the erect groove of the roof covering, this can also be joined in another way, e. g., by means of soldering to the roof cov- Fig. 4 shows that part Z; can move in the slots 0 of parta by the section 00 along the groove and the slope of the roof and that since part b is made of thin sheet metal, the flexibility or springing of same secures a transversal movement or swinging in a direction vertical to that of the first movement. The double arrows in Figs. 2 and 3 illustrate this possibility of swinging ormovmg.

Figs. 5 and 6 show a clinger, the erect part 7) of which is joined pivoting to the stationary part a, thus effecting for part 7) allowance for longitudinal displacement on j oint-' bolt (Z as well as for lateral swinging. The double arrows of Fig. 5 illustrate the swinging extent of the erect part b of the clinger, while Fig. 6 shows the longitudinal displacement by the section 00.

Figs. and 8 show a clinger. the parts of which both a and Z) are connected like ball joints which likewise secure a freedom o i motion in all directions parallel to the surface of the roof.

Figs. 9 and 10 show a further design which allows part b of the clinger to be tipped up and to be longitudinally displaced by a part d which shows the shape of a bolt. Also in. this case a displacement by the section 00 (Fig.

,2? f 1,ee2,105

) may take place in a direction vertical to the swinging plane of Fig. 9. i 7

Figs. 11 and 12 finally show a clinger in a design Which secures the freedom of 1110- v tion or flexibility intWo directions running vertically one to the other. Part I) is connected to part a by means of two steerers e of thin sheet metal. These steerers 6 allow on the one hand (Fig. 12) a swinging extendw ing over the section m, on the other hand, in

consequence of their thin material they allow, by means of springing, a deflextion in a vertical direction to the former swinging plane (Fig. 11.). p 15 I claim as my invention A clinger consisting of two principal parts for erect grooves in a flexible metallic roof, covering of which the one principal part is firmly connected to the base of the roof, and the other principal part to the roof covering, characterized by an elastic joint existing between the principal parts which secures freedonrof motion between the principal'parts' and thus also between the base of the roof and the covering of the roof along and vertical to the slope of the rooii'as described.
